TVS Eurogrip showcases what goes into the testing and improvement of their tyres.
Tires (carefully adopted by suspension) are simply essentially the most misunderstood and ignored component of a motorbike. Nevertheless, there’s a enormous quantity of science and engineering that goes into making good tyres, and TVS Eurogrip needed to enlighten us on this subject.
The occasion was cut up right into a classroom masterclass earlier than we headed out onto the racetrack to expertise what a tire tester’s job is like. There have been 4 specialists who’d share their information, particularly TVS Eurogrip CTO V Sivaramakrishnan, Renato Zilli, who runs the Eurogrip operation in Milan, and two of the corporate’s knowledgeable check riders. Each Toshihiro Wakayama and Vittorio Iannuzzo grew to become check riders after wealthy racing careers and had lots to share with us.
Renato Zilli, head of TVS Eurogrip Milan, together with check riders Vittorio Iannuzzo and Toshihiro Wakayama, discuss us by means of the complexities of tire testing.
Tire expertise can rapidly turn out to be an extremely sophisticated subject, however there have been some fascinating insights from the classroom session. Sivaramakrishnan defined that tire compound improvement works lots just like the pharmaceutical trade. That is as a result of, like with prescribed drugs, the search is continually on for brand new compounds that may greatest meet a desired set of parameters. Many of the compound improvement for TVS Eurogrip occurs of their new materials science laboratory in Madurai, together with inputs from Europe and Japan.
The corporate is already utilizing synthetic intelligence and simulations to give you new formulations. The very best of those formulations are then despatched to the manufacturing centre, the place prototype tires are made and examined for drivability in addition to sturdiness, and one of the best of these prototypes make it to manufacturing.
This course of takes about two years to get a finalized, production-ready tyre, however then it takes much more time to develop a number of sizes of that very same tyre. It is because totally different sizes create totally different improvement challenges in areas like the form and building of the tyre.
A lot of the preliminary tire design course of by way of tread design, profile form, compound materials and carcass building is nearly performed and lab-tested, however that may solely go up to now. That is why human check riders are so necessary; they return suggestions by way of how the tires really carry out versus how the digital instruments say they ought to carry out.
The Harley’s limits arrived far earlier than the tyre’s.
This can be a time-consuming and very methodical course of that occurs on a number of check tracks and roads throughout Europe, Japan and India. An enormous variety of parameters of a tyre’s habits by way of stability, braking, lightness, agility, grip, grip loss, and far more are documented.
The check riders additionally use a number of bikes (from the tyre’s goal style) and examine the prototypes towards benchmark tires from rival manufacturers which might be put in on the identical bikes. These are nearly all the time ‘blind checks’ the place the rider would not know what tire they’re on. The rider’s function is to guage the tires, catalog their outcomes and share that data together with their suggestions with the event engineers. Armed with this information, the event staff then distills the constructive facets of the varied prototypes into one remaining product.
With our heads full of data that’s too huge to doc on these pages, we headed to the Kari Motor Speedway to get a real-world really feel of tire testing. What awaited us was all kinds of bikes geared up with quite a few totally different TVS Eurogrip tire fashions. There have been no raging superbikes, and we had a really real-world set of bikes to attempt, with the quickest bikes I rode being a Kawasaki Versys 650 and a Harley-Davidson Avenue Rod.
The Protorq Excessive is without doubt one of the most spectacular Indian two-wheeler tires to this point.
With machines just like the RE Traditional 350, TVS Ronin and the Avenue Rod, the machines’ limits arrived far nearer than the tyres’. Fortunately, the Versys 650 allowed extra beneficiant lean angles, which revealed that the brand new Highway Hound sport touring tire has a really assured, linear and pure really feel with huge quantities of grip. In the meantime, the KTM 390 Duke jogged my memory that the Protorq Excessive is fabulous and simply one of the best Indian bike tire I’ve tried to this point.
It’s so good that it was chosen by Aprilia because the OEM tire for the brand new RS 457. The truth is, Eurogrip says that they acquired some useful insights whereas co-developing the tire to Aprilia’s specs. These learnings have been launched to all Protorq Extremes that are actually bought within the aftermarket.
On the finish of the day, we did not get to push these tires to the restrict, however we did get an perception into the depth of complexities concerned with making good bike tires.
